Gearbox repair

[xrhstosgr]

Hello
In the past few days I have removed the transmission from my Toyota Auris Diesel 12/2012 1ND MK1 6 speed car. The car shows 260,000 kilometers on the odometer. This was done at the local workshop in the city I live in and sent to Athens to a specialist workshop specializing in Touota transmissions to repair this.
2 bearings and the SASSMAN COUPLER (genuine 33361-20070) were changed. The 2 tapered bearings were not damaged
Visually, the bearings show no signs of wear. The compler, however, is broken and worn in two places as you will see in the photos. and in the video below. The broken pieces from the compler that broke, fortunately for me ΄΄ were carved ΄΄ into an empty spot inside the chassis and thus saved me further repair and many more expenses according to the technician.
The technician also mentioned to me that the Touota transmission clutch, especially the Auris Yaris Verco, are problematic, (they wear the same clutch code) pointing out that the way to change the gears, and specifically the first gear, should click when the car is to full absolutely immobilized completely, every time.
The reason I took down the shasman was the loud metallic noise near the area, which became more intense in the last 2-3 days. In total, the noise from the moment it started beating must not have exceeded 15 days.
I must note that the gears engaged normally, and the clutch disengaged normally, without giving the slightest of the above signs to trouble me more.
Are there people who have had similar problems?
I would also appreciate opinions and opinions from users who know these topics very well and I follow them
Thanks

You mention video and pics... Where are they?

And yes, 6 speed gearbox on those cars are somewhat troublesome. You can see that on other threads. But more of an annoyance rather than a true problem. Maybe the 1NDTV update, that makes the engine produce more torque (210 Nm vs 190 Nm) may have something to do with it, considering the lack of DMF.

looked up the part as the post is a bit lost in translation

you broke the 1st gear synchro clutch hub (sits between 1st and reverse) sounds like it was slammed in to reverse while going forward, or first gear gets a lot of abuse (hilly terrain and/or bad roads), a lack of inspection of the fluid or the gearbox fluid never being changed is another factor

Αναφέρεις βίντεο και φωτογραφίες... Πού είναι;

Και ναι, το κιβώτιο ταχυτήτων 6 ταχυτήτων σε αυτά τα αυτοκίνητα είναι κάπως ενοχλητικό. Μπορείτε να το δείτε σε άλλα θέματα. Αλλά περισσότερο ενοχλητικό παρά αληθινό πρόβλημα. Ίσως η ενημέρωση 1NDTV, που κάνει τον κινητήρα να παράγει περισσότερη ροπή (210 Nm έναντι 190 Nm) μπορεί να έχει κάποια σχέση με αυτό, λαμβάνοντας υπόψη την έλλειψη DMF.

Indeed the Nm torque is increased, as DMF and EGR have been removed. But are these reasons that caused these breaks of this code? (33361-20070) However, if you look at the photos, the spare part is very sensitive at the points where it broke

κοίταξα το μέρος καθώς η ανάρτηση είναι λίγο χαμένη στη μετάφραση

σπάσατε την πλήμνη συγχρονισμένου συμπλέκτη 1ης ταχύτητας (κάθεται μεταξύ 1ης και όπισθεν) ακούγεται σαν να χτυπήθηκε για όπισθεν ενώ προχωράτε μπροστά, ή η πρώτη ταχύτητα δέχεται πολλή κακοποίηση (λοφώδες έδαφος και/ή κακοί δρόμοι), έλλειψη επιθεώρησης Το υγρό ή το υγρό του κιβωτίου ταχυτήτων που δεν αλλάζονται ποτέ είναι ένας άλλος παράγοντας

The technician who repaired the transmission stated that the first gear the first gear coupler broke as it is too sensitive, and that these cars have this problem in general It states that I must bring the vehicle to a complete stop when engaging first gear. No, we will not drive on rough roads The fluid was never changed

[xrhstosgr]

When driving, the car had no problems, (except for a little noise as I mention in the topic) all gears and especially the first engaged normally. Is it possible for this to happen with a broken gear inside the box?

Στην οδήγηση το αμάξι δεν είχε κανένα πρόβλημα, (εκτός από λίγο θόρυβο όπως αναφέρω στο θέμα) όλες οι ταχύτητες και ειδικά η πρώτη μπήκαν κανονικά. Είναι δυνατόν να συμβεί αυτό με σπασμένο γρανάζι μέσα στο κουτί;

With the time, it is possible that the increased torque will increase the wear and tear. But yes, the 6 speed gearbox is not as robust as the older 5 speed gearbox. There are other threads on the forum, with issues about those 6 speeders. Vibrations, noises. Again, more annoyances than actual faults, but some faults, yes.

Με την πάροδο του χρόνου, είναι πιθανό η αυξημένη ροπή να αυξήσει τη φθορά. Αλλά ναι, το κιβώτιο ταχυτήτων 6 ταχυτήτων δεν είναι τόσο στιβαρό όσο το παλαιότερο κιβώτιο ταχυτήτων 5 ταχυτήτων. Υπάρχουν και άλλα θέματα στο φόρουμ, με θέματα σχετικά με αυτά τα 6 ταχύπλοα. Δονήσεις, θόρυβοι. Και πάλι, περισσότερες ενοχλήσεις από τις πραγματικές βλάβες, αλλά μερικά σφάλματα, ναι.

jcps001 thanks for the info

Removing the dual mass flywheel could have contributed to the damage, as the DMF springs would absorb some of the load shock when pulling off in 1st. But as others have said, it is a weaker gearbox than the 5 speed.

Η αφαίρεση του σφονδύλου διπλής μάζας θα μπορούσε να έχει συμβάλει στη ζημιά, καθώς τα ελατήρια DMF θα απορροφούσαν μέρος του κραδασμού του φορτίου κατά το τράβηγμα στο 1ο. Αλλά όπως είπαν και άλλοι, είναι πιο αδύναμο κιβώτιο από το 5άρι.

 

Solero was misinterpreted with DMF, I have not removed it as the translation was probably not done correctly. Could I install dual mass flywheels and be less likely to have this break in the compler avoid these problems?

Ok, clutch probably does not come with DMF originally. I dont think you can put one in. Ignore my comment.
